Pierce Brosnan believes working with Robin Williams was "sheer magic."
The 61-year-old hunk is devastated following the tragic death of the comedy legend earlier this week, but he is determined to treasure the memories he made with the late star whilst starring alongside him in 'Mrs. Doubtfire.'
Speaking to Us Weekly, he said: "It is a deeply sad time for us all on the loss of Robin Williams.
"My first day on [the 'Mrs. Doubtfire'] set [in 1993], they said, 'Do you want to meet Robin?' I had never met the man, I was so excited. I was so thrilled to have this job in the company of this great star comedian.
"I walked into the trailer and there was Robin in a pair of Ugg boots, hairy legs, shorts, Hawaiian shirt and hairy chest. That's how I met Robin Williams, and that's how I met 'Mrs. Doubtfire.' And I had the time of my life.
"Every day was just sheer magic with the man. His hilarity, his grace, his brilliance of mind and soul. His reverence, sincerity. [It's a] deep loss."
However, the former 'James Bond' star is adamant Robin's memory will live on and he will be "forever" loved and missed in the entertainment world.
He added: "It really has cut deep into all our hearts that he is gone and that he suffered in such pain. He will be loved forever and missed forever."
Robin, 63, is to be laid to rest in San Francisco after committing suicide at his home address in Tiburon, California, on August 11.
He leaves behind his third wife of three years Susan Schneider and his children Zak, 31, Zelda, 25, and Cody, 22.

Kim Kardashian West's daughter loves swimming.
The 33-year-old reality TV star admits 14-month-old North is a natural in the water and she enjoys watching the youngster splash about in her weekly lessons.
Speaking to PEOPLE, she said: "It's so fun to see her take swim class. She loves the water in general - she really likes to have fun."
The brunette beauty believes the toddler's biggest milestone to date is learning to walk and she and her husband Kanye West, 37, are glad they were both there to witness their daughter take her first steps last month.
She recalled the special moment: "She was so excited to have this apple that she would swim around the pool to get it. Then we took her out, and she just walked [her first steps] toward the apple! We were like, 'She walked!' It was so exciting!"
Kim announced the little one had walked for the first time unaided on her Instagram account shortly after the event in July.
She posted an adorable picture of her kissing North, who was wrapped in a yellow towel, along with the caption: "Our baby girl finished one week of swimming lessons today then took her 1st steps right when she got out of the pool!!!! Mommy & Daddy are so proud of you!!!! Photo cred: Daddy (sic)."
Meanwhile, not only has North surprised Kim with her swimming ability, she's also developed an obsession with music and loves joining her father Kanye in the recording studio.
A source said previously: "She loves music and is obsessed with hearing it in the studio."

Robin Williams' wife has revealed he had Parkinson's Disease at the time of his death.
Susan Schneider admits her husband, who committed suicide earlier this week, was in the "early stages" of the illness but was not ready to announce it publicly.
She released a statement, saying: "Robin's sobriety was intact and he was brave as he struggled with his own battles of depression, anxiety as well as early stages of Parkinson's Disease, which he was not yet ready to share publicly."
Robin, 63, was found at his home in California with a belt wrapped around his neck on August 11 and Susan hopes his tragic death will encourage other people to seek help before their own troubles become too much.
She added: "It is our hope in the wake of Robin's tragic passing, that others will find the strength to seek the care and support they need to treat whatever battles they are facing so they may feel less afraid."
Meanwhile, Susan is reportedly planning a "very private" funeral in the Bay Area of San Francisco for the 'Mrs. Doubtfire' star, and family members, including his 31-year-old son Zak, have begun flying into town ahead of the service.
It is believed the memorial will be intimate and for close friends and family - including his younger children Zelda, 25, and Cody, 22 - only.
A source said: "It's not official yet, but that's the plan. It will be small. They were both very private people."

Guy Pearce has confessed he has an addictive personality.
The Australian actor - who stars in 'The Rover' alongside Hollywood heartthrob Robert Pattinson - has previously confessed to having a problem with cannabis and although he no longer smokes the herbal drug he concedes he is always addicted to something.
Guy, 46, explained: "There's always a few things, but these days they tend to be healthier. I'm very aware of it.
"Even now, I'm drinking a coffee. I haven't drunk a coffee for years, and just in the past 12 months I've started drinking it again. I feel myself going, 'Yeah, I'll have another one, I'll have another one, another one.' Why can't I just have the one in a day?"
Asked about the recent global rise in legal marijuana, the 'Lockout' star said: "I have to be careful what I say. I can't be out there going, 'Drugs are great, man!' I have mixed feelings.
"On one level I think it should be legal and everybody should be able to do what they want, but on the other hand I'm aware that a massive percentage of the population can't handle it and do crazy things and hurt people or hurt themselves. So you can't generalise."

Simon Cowell is making a Betty Boop movie.
The music mogul's Syco Entertainment company and Animal Logic Entertainment are working together to bring the iconic cartoon character back to life on the big screen.
According to Variety, confirmed producers are Zareh Nalbandian and Jason Lust from Animal Logic - who were responsible for the animation on 'The Lego Movie' - and Cowell and Adam Milano from Syco. There is no director or writer attached to the project yet.
Cowell confirmed the news on his Twitter account, writing: "I've worked with some serious divas but I think Betty could be the biggest of them all! @bettyboopnews (sic)"
The post was accompanied by a photo of 'The X Factor' judge being silenced by Betty, who had her hand over his mouth.
The movie will be a hybrid project featuring live action and animation and it will also contain several songs.
Jazz flapper Betty made her first appearance in the black and white cartoon 'Dizzy Dishes' in 1930 and went on to feature in over 100 cartoons with her catchphrase "boop-oop-a-doop" becoming famous worldwide.
The bobbed-hair, short-skirted character also made a cameo in the 1988 Disney hybrid film 'Who Framed Roger Rabbit'.
Syco Entertainment and Animal Logic brokered a deal with Fleischer Studios - the company founded by Betty Boop creators, brothers Max Fleischer and Dave Fleischer - to make the movie.
Speaking about the deal, Mark Fleischer, chairman and CEO of Fleischer Studios, said: "I am delighted to partner with Syco Entertainment and Animal Logic. Their energy, creativity and playfulness make them a perfect fit for Betty Boop."
The Betty Boop movie is Cowell's latest foray into films following
the 'Pudsey the Dog' movie and Paul Potts biopic 'One Chance', which starred James Corden.
The star has previously admitted he watches cartoons everyday to relax when he's not working.

Sir Cliff Richard has been aware of sex offence allegations against him for "many months".
The 73-year-old star has released a statement following the news earlier today (14.08.14) that a property belonging to him in the Sunningdale area of Berkshire, South East England had been searched by police in relation to an alleged historical offence.
He said: "For many months I have been aware of allegations against me of historic impropriety which have been circulating online.
"The allegations are completely false. Up until now I have chosen not to dignify the false allegations with a response, as it would just give them more oxygen.
"However, the police attended my apartment in Berkshire today without notice, except it would appear to the press."
The 'Summer Holiday' hitmaker - who is currently believed to be residing at his home in Portugal - went on to reiterate that he disputes the allegation and claimed he would be more than willing to help the police with their investigation.
He added: "I am not presently in the UK but it goes without saying that I will cooperate fully should the police wish speak to me.
"Beyond stating that today's allegation is completely false it would not be appropriate to say anything further until the police investigation has concluded."
Sir Cliff's home was searched in connection with an allegation of a sexual nature dating back to the 80s involving a boy under the age of 16, but no arrests have been made, according to a statement from South Yorkshire Police.

French Montana says the public's perception of his girlfriend Khloe Kardashian doesn't chime with the reality.
The 'Ain't Worried About Nothin' rapper has been seeing Khloe, 30, for several weeks, and he insists she is very different to how she is portrayed in reality TV show 'Keeping Up with the Kardashians'.
He told the New York Daily News newspaper: "That's my Koko. She's a real cool down to earth person. I don't think a lot of people get to meet her to find that out."
Montana, 29, also vehemently refuted suggestions he is dating Khloe as a means of boosting his own profile.
He said: "I don't look at it like that. She's the funniest person ever."
Montana also defended the rest of the Kardashian clan, saying: "When you're in the limelight and you're in that kind of position in life you're always going to have haters.
"I feel like once you get to know [the Kardashians], they're really like (some) of the dopest people ever."
Khloe makes a guest appearance in Montana's latest music video 'Don't Panic', which debuted on Wednesday [13.08.14].
Montana said: "It's the first video she ever did and it got a little spike."

Scarlett Johansson found it "challenging" to play the central character in new film 'Lucy'.
The flick - which also stars Hollywood legend Morgan Freeman - follows the story of Scarlett's character, whose brain becomes extraordinarily powerful after she becomes a drugs mule for her new boyfriend.
The actress admits she found filming the much-hyped flick to be an "intense" experience because there were "no guidelines" for the role, telling BBC Radio 1: "We shot part of the film in Taipei [Taiwan], which was very exciting.
"Even making it everyday, sort of, you know, brought on its own unique challenges because the character was losing the sense of her own humanity as she's gaining all of these superhuman abilities.
"So there was kind of no guidelines for that. I never knew what I was going to be stepping into each day. The whole shoot had a level of surrealism to it, I suppose."
She added: "It was sort of an abstract experience. I don't know, I enjoyed it."
Scarlett, who is rumoured to be expecting her first child with fiancée Romain Dauriac, also revealed she has just finished shooting her scenes for the 'Avengers' sequel.
'Lucy' opens in UK cinemas on August 22.

Plans to make 'Bad Boys 3' are progressing, according to Martin Lawrence.
The comedian, who starred in the first two films in the franchise alongside Will Smith, revealed the news during an interview with US talk-show host Conan O'Brien.
Asked whether 'Bad Boys 3' will happen, the 49-year-old said: "I believe so. Yes."
He added: "I just talked to [producer] Jerry Bruckheimer and he said it's real, they're working on the script, they're getting close and it all looks good."
One of the biggest obstacles to making the film will be getting co-star Will Smith on board - an issue Bruckheimer discussed in April.
He said: "It's so funny because we'll get Sony real excited to make the movie, and then Will is off doing two movies. And then, Will will come back and be real excited about it, and Sony will say, 'Well, maybe it's not the time for this.'
"And then, 'Ride Along' came out and was a big hit, and now they're all excited to make the movie, but Will is off doing something else. It's just trying to get everybody together to make it. But, we're working on the script. We have a lot of faith and hope that we'll do it."

Nile Rodgers says the songs he's working on with Duran Duran are sounding "sick".
The Chic guitarist-and-songwriter is in the studio with the band and producer Mark Ronson recording tracks for the group's next album.
So far, Nile can't believe how good the tunes they are laying down sound and he is thrilled to be working with Duran Duran again after first collaborated in 1984 on a remix of hit single 'The Reflex' and then on their 1986 album 'Notorious'.
He wrote on Twitter: "This is turning out so good it's sick! Nile Rodgers & Duran Duran."
In earlier posts, the 'Get Lucky' hitmaker enthused about the band's professionalism in the studio and immense musical talent of singer Simon Le Bon, keyboard player Nick Rhodes, drummer Roger Taylor and bassist John Taylor.
He tweeted: "So awesome to be in a real studio recording with a real band! @duranduran @iamMarkRonson @nilerodgers ... In writing with Duran today I said, "Let's change one chord to a
G-7b6" and Nick played it instantly! proud (sic)"
Nile, 61, was a friend of Ronson's family and watched the future producer-and-musician grow up.
The disco legend is delighted he is now getting the chance to record with Ronson, 38.
He previously said: "I gave Mark Ronson his first Walkman and he started bouncing on one foot and then the other and then started becoming a producer. Can you imagine what it's like having me and Mark in the same room as Duran Duran? The love is insane."
